Description
Technical field
The present invention relates generally to a kind of and internal combustion (IC) engine camshaft and supporting flexible chain actuating unit and the installation method thereof of annex.The present invention be more particularly directed to help to improve space efficiency and improve flexible chain transmission device integrated of motor assembling.The present invention be more particularly directed to will with supporting flexible chain actuating unit of car combustion engine and enclosure group dress up be an integral unit that can separate from supporting motor with and used method.
Background technique
A part of mechanical energy that internal-combustion engine requires to obtain at their bent axle place usually is passed to and the irrelevant device of motor main purpose.Described main purpose comprise to vehicle provide power or stationary application provide be converted into electric energy or liquid can energy.Some devices wherein are called as engine accessory power rating or auxiliary device.In these annexes, has the device that to realize motor ongoing operation required function.These devices comprise the oil pump that is used for motor is provided oil pressure, fuel pump to the fuel oil pressurization that is supplied to Carburetor or injection system, increase the pressurized machine of mainfold presure, permanent magnet generator provides generator or the alternator of ignition spark and makes the water pump of circulate coolant by engine-cooling system.
Also there is the annex to realize with the irrelevant function of motor main purpose or motor continuous firing.The example of these annexes comprises in order to the power steering pump to the servo steering device pressurization, provide (not comprising ignition system) generator or the alternator of electric energy to the electronics of vehicle, be used for the vacuum pump and the air condition compressor of power distribution to some Vehicular system.
The mechanical energy that also must excavate bent axle continually is used to control the valve that engine gas flows with manipulation.Usually, it comprises power from the synchronous transport of bent axle to one or more camshaft, and it can make valve work in the time control mode.
For all but the simplest motor, the power transmission system of having used gear drive or flexible chain to drive drives generator annex and valve train.The flexible chain power transmission system comprises that those are equipped with asynchronous power transmission belt, the system of synchronous dynamic driving belt and chain.
Drive system model or train of gearings are in the layout of drive unit and have limited flexibility in the mutual geometrical relationship of annex, camshaft and bent axle.Must according to axially locating with separate and plane positioning, make gear keep accurate relation each other.Equally, existence can change the limited overall geometry of power takeoff point with respect to the layout of bent axle.Train of gearings often also can produce excessive unwanted noise.In addition, this train of gearings requires the lubricated of motor overhauled usually.But train of gearings can be carried sizable power with various rotational velocity.Therefore, to being used for the application, particularly compression ignition type of the motor that the large-scale heavy duty operating conditions uses, as heavy truck, train of gearings has reached their greatest acceptance.
The common requirement of this wheel system used a plurality of idler gears, and these gears also must be installed on the motor, thereby causes providing the problem of correct supporting and driving complicated more to valve train and engine accessory power rating.Because must drive rotational velocity and these valve trains and the very high torque request of annex existence of engine valve train and annex, each gear that therefore constitutes power train must have very high precision.If very carefully do not position the correct backlash of guaranteeing between the engaging tooth, then can not realize the performance level of this high quality train of gearings fully to constituting each gear that drives system.The failure that obtains desirable backlash can cause the grievous injury of wheel tooth, thereby requires train of gearings is carried out maintenance expensive and consuming time.
Narrow limitation and the requirement having adopted a large amount of mount schemes to make great efforts to adapt to emphasize above.For example, in some motor, directly auxiliary drive gear is installed on the cylinder block of motor, still, directly gear is installed on the cylinder body of motor and requires on cylinder block, to process vestibule to receive the axle of annex and idler gear.In addition, these vestibules are with respect to bent axle, camshaft and must have accurate distance each other.Also can produce out of use cylinder body even the machining error of a vestibule occurs, these out of use cylinder bodies must go out of use and cause very big waste.Even when vestibule is correctly located, also need independent positioning equipment to obtain correct backlash.
Another kind of scheme is to make a kind of main machine frame, and all gears of train of gearings have been installed on it, and these gears comprise crankshaft gear, and equipment gear and camshaft gear wheel are so that dress up a unit with all these gear trains.Subsequently this unit is installed on the cylinder block, so just allows, and eliminated the needs that directly on cylinder block, accurately add work gear with desired accuracy relation assembling and maintenance gear.But still must gear shaft receiving bore be located on main machine frame.But, if machining error, this main machine frame can't use so.For the manufacturer of the discarded not main frame of correct perforate, this cost is far below the discarded cost that correctly engine cylinder is not carried out perforate.
In addition, because the requirement of said gear system, therefore, be very unpractical in the piecemeal removal and the replacing of annex and their associated gear.This mode has been applied to some annex is installed on the main frame.The U. S. Patent 1,647,434 of Chorlton has just disclosed this structure.
The flexible chain power transmission system that drives annex and valve train does not face these limitations and requirement.Therefore, greatly reduce the pinpoint demand of idler gear, actuation gear or annex.In whole very wide position range, annex and camshaft can be set.Shortage can cause the dismounting one by one and the replacing of annex to the requirement of train of gearings accuracy.Equally, flexible chain transmits, and it is often quiet that particularly those have utilized the transmission of dynamic conveyor belt.
In the application of motor car engine, these characteristics have made flexible chain power be transmitted in and driven in annex and the valve assembly has advantage.Recently, modal structure is that each annex is installed in independently on mounting points or the carriage, is installed on the cylinder block or cylinder head of motor.Subsequently, one or more asynchronous dynamic conveyor belt is inserted into each driving wheel supporting with each annex from the crank-driven wheel.The driving wheel supporting with asynchronous dynamic conveyor belt is belt pulley or pulley.Equally commonly tension device is installed in respectively on the cylinder block so that the tension force on the line belt to be provided, to help the correct location of actuating unit.
Usually, camshaft is arranged in the cylinder head of motor.Driving wheel is fixed on the camshaft.Subsequently, an auxiliary flexible chain is inserted into the camshaft actuated wheel from the crank-driven wheel.Because camshaft is synchronoused working with bent axle, therefore, flexible chain can adopt a synchronous dynamic line belt or a chain.In any case, the driving wheel that is used for bent axle and camshaft is sprocket wheel.As accessory drive system, camshaft drive has also utilized the tension device that is directly installed on cylinder block or the cylinder head to come the tensioning flexible chain, to help the correct work of described drive unit.Usually, the front surface by motor and front engine cover cooperates to hide the flexible chain camshaft drive.Can protect described drive unit to avoid the influence of some external factor (as dust, sandstone and water) like this.
Be used for the alternative scheme that each annex is installed on the carriage is independently comprised and will be used for the part of the mounting points of annex as protecgulum.People's such as Hausmann U. S. Patent 5,692,466 has just disclosed this scheme.This scheme shows and have the following advantages, that is: 1) omitting usually, used attachment supports frame can reduce cost and weight; 2) guaranteed installation strength, transmitted thereby can form good reaction force to annex; 3) improved the resonant frequency of camshaft drive cover, it can reduce the vibration of annex greatly and reduce the noise of motor, 4 during engine operation) simplified the cast structure of cylinder body front surface.But Hausmann does not mention or advises at first annex being installed on the cylinder head, and the assemblying body with cylinder head and annex is installed on the cylinder block subsequently.
Another kind of scheme provides a kind of integrated type mounting bracket that is used for engine accessory power rating.Should select the part in all annexes relevant and they are installed on the carriage with any given motor.Subsequently, carriage and these assemblies are installed on the engine cylinder as an integral unit.Be installed on the bent axle by the belt pulley of independent operation bent axle.In case finish these work, just dynamic conveyor belt be installed subsequently around belt pulley.This scheme obviously attempts to obtain a kind of advantage of modified model assembling method, thereby reduces the required step number of main assembly line work and reduce quantity in stock.
But, also do not have a kind of scheme separately or to combine and realize the obtainable whole advantages of highly integrated flexible link power transmission system among the present invention.These advantages comprise the quantity that reduces the main assembly line step and reduce inventory part in addition.Importantly, the present invention can be provided for improving the possibility to driving wheel control, improves the wearing character of noise and flexible chain.This improved control can also provide the possibility of strict control size tolerance, thereby compacter drive unit is provided.Synchronizer requires clean, and with regard to chain drive, also requires good lubricated environment to produce satisfied result.Another advantage provided by the invention is the sealing that allows the sync section of the supporting drive unit of improvement and camshaft, thereby reduces the intrusion of extraneous foreign matter and the leakage of oiling agent.
All these advantages all are very desirable for the automaker.They can cut down assembly cost.They can also allow power equipment littler, and itself can allow to use littler engine compartment again, thereby can be with bigger inner space as selling point for the automobile of given size.The noise that is produced and the reduction of wearing and tearing can improve the sensation of Consumer to quality and maintenance, and have reduced repair rate.
Therefore, there is demand, on described engine-driving frame: be equipped with in advance all or roughly whole annex, comprising supporting driving wheel to the highly integrated flexible link power transmission system that the engine-driving frame is housed always; In order to prepare finally to be installed on the motor, all other driving wheel is installed; The formation of auxiliary drive is included in flexible chain is set on the driving wheel; The formation of separating with auxiliary drive or forming the camshaft drive of part auxiliary drive comprises around sprocket wheel flexible chain is set; And camshaft drive provided the environmental protection that improves.
